First of all: Congratulations to your verry informativ Website.
My Name is Wolfgang and i am from Switzerland.
As you can see on my Homepage i work with Peter Müller from History Facts on a Book to the StuG III.
Now i have a Question about the Big square Towebar underneath the Exhausts on the StuG III G.
On the Pictures from Ps- 33,-34,-38,-53 an -57 i can clearly identify the Bolts for holding this Towebar on the Rear Hullplate.
I also have seen this Bolts on the StuG III G in Thun ( Switzerland) but the Towebar was not in Place.
The StuG III G in Munster has the Towebar.
Now my Question :
Are this Bolts on the finish StuG III from the 1944 Batch a finish modification or are the original ?
Because the StuG in Thun shows with the same Configuration the MIAG Zimmerit.
And this would be a Tipp that this Towebar would be in service from about June 1944 and not as published so far from Dezember 44.

Thanks for your answer Andreas But there is another one Question i found as i was looking the Pictures on your Website.
It seems that on the lower rear Plate besides the big Cover ( lubrication Crankshaft Ventilators) another small one hole was. And this looks to me as it would be closed by welding a Plug in. By the Ausf A this smale Hole was there for draining Water of the Cooling System.
For example PS 531 - 8, - 6, -19 .

Do i see this correct or do i have "Halluzination" ?
Do you have any information about this "closed Hole " ?

Lower is cover for "preheating system". If you look closely, you should be able to see "fins" in hole. Pre heating system was operated with blowtorch. Warming water started to circulate and hot air was then blown to oil tank... (see link)
